Well, I'm not an MD, but I did study biology in college, to my recollection the
inverse ghost image you see after staring at something a while is caused not by
a neural mask, but rather by chemical fatigue of the receptor cell itself.  Red
receptors, for example, become chemically depleted when constantly stimulated
for a period of time.  Their output is then diminished until the chemical
balance in that cell is restored, which takes a minute or two.  All of the
other, less stimulated receptors then produce a larger signal in comparison,
producing what is perceived as a color reversed ghost image of what had been
stared at.

But that's the eye, I can't speak to your theory about a drummer.

I still say that a mildly randomized track sounds better than a quantized one.
